[BEEROVED BRICK-MACHINE.

The Schedule referred to in these'Lettera Patent and making part of the um To all whom it ma/yconcern:

Beit known that we, J. G. LEER and H. D. THonP, of Harlan, in the county of Allen, and State of Indiana, have invented a new and useful Improvement in Brick- Machines; and we do hereby declare that the following is a full, clear, and exact description-thereof, which will enable others skilled in the art to make and .use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side View' of our invention, partly in section.

Figure 2 is a vertical section of the liney aix, g. 3.-

lFigure 3 is a plan or top view of the same, partly in section.

Similar' letters of reference indicate corresponding parts.

This invention relates to a new and improved ma,- chine for moulding and pressing brick.

It consists in a peculiar construction and arrangement of parts, as hereinafter fully shown and described, whereby a very simple, economical, and edicient machine for the purpose specified is obtained.

In' the accompanying sheet of drawingsv A represents the frame of the machine, which may be constructed in any proper manner, to support the working-part; and

B is the case of the mud-mill, fitted in frame A, and having a shaft, G, placed centrally and vertically in it, to which arms a are horizontally attached, for grinding and tempering the clay. ,I

To the upper end of the shaft G, a sweep, D, is attached, to which the animal which operates the machine is connected.

In the bottom of the mud-mill, there are fitted two metal gratings E E, the cross-bars l1 of which are ver,. tical at one side, and inclinedat the other side, as shown at l in iig. 2, and the clay is forced through these gratings, into the moulds underneath them, by

the same, taken in lmeans of wide pressers F F, which are somewhat inclined in their` transverse section, said pressers being attached to the lower part of shaft C, so as to work quite closely to the gratings. Y

G G represent'two tables, on which the moulds rest while .being filled or having the clay forced into them.

These tables are attached, at their inner ends, to the frame A by joints c, which admit of the outerparts of the tables being raised and lowered, the tables being raised, and' supported when in a raised state, by bailshaped rods or bars 'H H, the lower ends of which are connected, by joints d, to the frame A.'

The sides of these bail-shaped rods or bars are curved inward underneath the tables, to form horizontal portions e, on which the tables rest. (See fig. 2.) .By

turning up the bars'H to a vertical position, the tables will be supported in a horizontal one',- and, byl turnin said bars outward and downward, the Aouter 'parts o the tables will be lowered, as shown in fig-1.

Between the inner ends of the two tables G there is a fixed table, I, on which the empty moulds are placed from one Aside of the machine, and at the opposite sides of the frame there ar'e horizontal slide-bars J J, at right angles with the xed table I, and having arod, K, attached, which is overthe table I, and works from one side to the other of the same, under the motion of the slide-bars J J.

The slide-bars J J are operated from the sweep D, as follows:

v L is a shaft, which is fitted inthe lower part of the frame A, and has a lever, M,at each end. y

These levers extend upward at the sides-0f the machine, so that theyT may be acted upon by a latch, N, attached` to the sweep.

This latch N is constructed of a bar, pivted, at-

one end, to a pendant, g, of the sweep, and passing through a guide, h, attached to the sweep, the bar being kept down in contact with .the bottom of the guide by a spring, t'.

As the sweep D is rotated, the bar f comes in contact with the upper ends of the levers M M, moving first one and then the other, the bar f being raised from the levers at the proper time, in consequence -of coming in contact with curved rods O O onthe top of frameiA,'the position of said curved rods O O determining the length of the vibration of the levers.

By this arrangementya reciprocating movement is given the rod K, and the empty moulds moved under the gratings E E, where they are filled, or have the clay forced into them, imder the action of the pressers F F. The filled moulds are shoved out from underneath the gratings by the passage of the empty'onesunderneath the same. y

By having one side, l, of the cross-bals b of the grat ings E E inclined, the mud is forced through the gratings with the least possible degree of friction.

Having thus described our invention,

We,4 claim as new, and desire to secure by Letters Patent- The levers M M, slide-rods J J, with rods K attached, in combination with the latch N. on sweep lI), all being constructed and arranged for operating .the brick-moulds, substantially as shown and described.
